A. Astrology is definitely a perfect science; however it needs a proper brahmana to explain that. Previously brahmanas were having purity and intuition to predict certain events. However in Kali-yuga it is difficult to find that. If someone is in Krishna consciousness, then he/she is completely under the control of Lord Krishna’s internal energy. Lord Krishna decides what is best for His devotees. Since He is the Supreme Controller of all planets, He may change the position of planets for His devotees. When someone is in Krishna consciousness one need not fear or be anxious, but simply depend on Him.
